At a fancy restaurant brunch costs $17.50. As the cost of ingredients rises, the cost of the brunch also rises by 40%. What is the new price of the brunch?

Respuesta :

Answer:

Step-by-step explanation:

Use proportions.  

40 over a 100 because its a percentage. Then 17.5 over X because we're using X as a variable for the unknown total, of the new price for brunch.

Then you'll just cross multiply 17.5 by 100 which is 1,750 then divide it by 40 which is $43.75.

So your answer will be $43.75.
